Study to Validate and Test the Turkish Version of the Situational Vertigo Questionnaire for Adults with Vestibular Dizziness

What this Trial Is About

Researchers are evaluating the Turkish version of the Situational Vertigo Questionnaire SVQ to determine its validity and reliability for assessing dizziness symptoms often triggered by visual or environmental factors in people with vestibular conditions. The study is designed as a methodological scale adaptation and psychometric evaluation involving adults aged 18 and older who experience situational dizziness and can read Turkish. The Turkish adaptation process involves a detailed back-and-forth translation method to ensure linguistic and cultural accuracy. After developing a preliminary Turkish version, a pilot test with 20 participants will assess clarity, followed by revisions as needed. The final version will be used in a larger group to evaluate its psychometric properties. Participants will complete the SVQ along with other assessments such as the Dizziness Handicap Inventory DHI, Vertigo Symptom Scale VSS, and a Visual Analog Scale VAS for satisfaction. A subgroup will retake the SVQ after 7-14 days to assess test-retest reliability. Participants will provide written consent and complete surveys on their dizziness symptoms and related factors like medical history and daily activities. Researchers will collect detailed sociodemographic and clinical data to support analysis. No invasive procedures are involved. The main outcome measure is the SVQ score at baseline and follow-up, with secondary measures including DHI and VSS scores. Data confidentiality will be maintained, and findings are expected to support clinical evaluations by providing a reliable dizziness assessment tool in Turkish.
